Bursting Strength Tester

Mangal Instrumentation offers a Bursting Strength Tester designed to find bursting strength of fabric/leather/paper/paper board. Different models are available in the range. A test specimen is held between two annular clamps under sufficient pressure to minimise slippage. The upper clamping surface, which is in contact with the test specimens, has a continuous spiral grooves. A circular diaphragm of pure gum rubber is clamped between the lower clamping plate and pressure cylinder so that before the diaphragm is stretched by pressure underneath it the centre of its upper surface is below the plane of the clamping surface. The equipment is fitted with a motor driven cam mechanism, which increases fluid displacement on the lower side of the diaphragm at a specified rate. The equipment is fitted with an arrangement, which automatically brings down the pressure and stops the motor on completion of the test cycle. A maximum reading type pressure gauge gives the bursting pressure. For conducting tests on material where one pressure gauge does not cover the full range of loads encountered with the desired accuracy in measurement, a special model fitter with two pressure gauges with an isolating valve can be offered. Digital type pressure gauge type instruments are also available. Digital type pressure gauge with pneumatic clamping model also available. The company also offers Gauss/Tesla Meter, Haze Meter, LED Luminous Flux Meter, Gloss Meter, etc.
